NCI-H446 [H446] cell line | CL-0401 | Gentaur US, UK & Europe Disrtribition

Media: CM-0401

Organism: Homo sapiens, Human

Application: N/A

Background: This cell line was established in 1982 by D. Carney, A.F. Gazdar and associates from the pleural fluid of a patient with small cell cancer of the lung. The original tumor morphology was not characteristic of small cell lung cancer. The cell line is a variant small cell lung cancer in biochemistry and morphology, and expresses neuron specific enolase as well as the brain isoenzyme of creatine kinase. None of L-DOPA decarboxylase, bombesin, vasopressin, oxytocin or gastrin releasing peptide has been detected in the cell line. This cell line exhibits a 20-fold higher degree of c-myc DNA amplification and a 15-fold higher degree of c-myc RNA. The cell line was originally propagated in serum free RPMI 1640 medium supplemented with 10 nM of hydrocortisone, 5 µg/mL of insulin, 10 µg/mL of transferrin, 10 nM of 17-beta-estradiol, and 30 nM of sodium selenite. Transplantable tumors with non-typical small cell lung cancer histology can be formed by the cells.

Age: male, 61 years

Tissue: Lung; Derived From Metastatic Site: Pleural Effusion

Morphology: Epithelial-Like

Growth Properties: Mixed, Adherent And Suspension

Doubling Time: N/A

Biosafty: 1

Medium: RPMI-1640(PM150110)+10% FBS+1% P/S(PB180120)

Subculturing: Remove and discard culture medium. These cells grow as a mixture of floating and adherent cells. Sometimes many cells are floating, they can be harvested by centrifugation of medium instead of discarding it. Add 1.0 to 2.0 mL of 0.25% (w/v) Trypsin-0.53mM EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 2 to 3 minutes). Add 4.0 to 6.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Incubate cultures at 37°C.

Ratio: 1:3 to 1:4
